Abstract

Un sistema vibrador para ser usado en un dispositivo para la grabación o exploración de una pista en forma de surco en que dos oscilaciones ortogonales son grabadas o exploradas respectivamente por medio de un miembro grabador o explorador común, comprendiendo este dispositivo un circuito magnético, en cuyo entre hierro útil es producido un campo magnético homogéneo, comprendiendo el conjunto vibrante por lo menos dos conductores de corriente y estando conectado con el miembro común, y estando provistos medios elásticos para volver de nuevo al conjunto a su estado de equilibrio, caracterizado por el hecho de que cada uno de los conductores de corriente consiste de un paso de corriente único, siendo por lo menos dos de dichos pasos perpendiculares uno al otro.
